Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a roadbed expansion soil improvement and processing device. Background Art

[0002] In urban construction, an important task is road construction. For some special road surfaces, the use of ordinary roadbed is not suitable. In serious cases, it is easy to cause road collapse during subsequent use of the road surface.

[0003] For expansive soil areas, during road construction, the expansive soil will swell when it comes into contact with water, causing its volume to increase, thus affecting the road surface during use and affecting the stability of the roadbed.

[0004] At present, the improvement method used for the above problems is to add cement. By adding cement in a certain ratio, the characteristics of the expansive soil can be improved and the bearing capacity of the bottom layer can be increased. During construction, cement is poured into the expansive soil, and then workers use sticks and other stirring tools to mix the cement and expansive soil evenly, and then use a paver to spread and level the soil. This method requires a lot of manpower, and because the road surface is wide, the center part of the road surface may not be able to be mixed carefully during manual mixing, resulting in uneven mixing. In subsequent use, the road surface will still collapse due to the water absorption of the expansive soil, affecting the stability of the roadbed. Utility Model Content

[0010] Furthermore, a roller is provided on one side of the vertical scraper, and two sides of the roller are respectively connected to the vertical scraper through a connecting rod.

[0011] Furthermore, the reciprocating motion mechanism includes a moving frame arranged inside the slide groove along the length direction of the slide groove, and a plurality of limit rods arranged on the inner wall of the slide groove in the width direction of the slide groove, the surface of the limit rod is in contact with the moving frame, the lower surface of the outer frame of the moving frame is connected to the slider, and a row of chain teeth are respectively arranged on the upper and lower surfaces of the inner frame of the moving frame, the chain teeth are meshed with incomplete gears located in the inner frame of the moving frame, and the incomplete gear is driven to rotate by a motor, and the motor is fixed on the groove wall in the length direction of the slide groove, and the motor is electrically connected to a power supply.

[0015] Furthermore, the shapes of the agitators are different from each other.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] The utility model provides a roadbed expansive soil improvement and processing device, which is used for mixing cement poured into an expansive soil road surface with a stirrer, so that the expansive soil and the cement are fully integrated, thereby achieving the effect of hardening the road surface and ensuring the stability of the roadbed. The utility model is based on a horizontal support plate located above the road surface and a slider sliding left and right on the lower surface of the horizontal support plate, so that the stirrer can evenly mix on various parts of the road surface. At the same time, a reciprocating motion mechanism can make the slider on the lower surface of the horizontal support plate, so that the stirrer can move in the horizontal direction when mixing, traverse various parts in the width direction of the road surface, and achieve uniform mixing and improve construction efficiency.

[0018] The utility model discloses a device for improving and processing expansive soil of roadbed. By combining the vertical support rod and the L-shaped support rods on both sides thereof with the limit strips placed on both sides of the road surface, the horizontal support plate can always move along the axis of the road surface without deviation when moving along the road surface.

During the construction process, the construction personnel can push the device provided by the utility model along the length direction of the road surface, thereby achieving uniform stirring of all positions of the road surface.

[0028] In the device of the utility model, the reciprocating mechanism, the telescopic device 7 and the agitator 7 all need to be electrically controlled, wherein the telescopic device can be a hydraulic device or an electric push rod.

[0029] In the present invention, an inverted L-shaped support rod 3 is further provided at the bottom of the vertical support rod 2, and a second roller 4 is provided at the bottom end of the L-shaped support rod 3. The L-shaped support rod 3 is located outside the projection of the horizontal support plate 1 in the vertical direction.

[0034] During implementation, the rotation of the motor 18 causes the incomplete gear 17 to rotate, thereby causing the moving frame 14 to move left and right under the drive of the sprocket 17. The power supply can be installed at a suitable position of the device according to actual conditions.

[0035] Furthermore, there are at least four limit rods 16, which are respectively located around the incomplete gear 17 and have a set distance from the sprocket 15. In this way, the position of the moving frame 14 can be kept unchanged in the horizontal direction.

[0036] In the present invention, the telescopic device 7 is a telescopic rod with adjustable length and limitable position. The stirrer 6 includes a plurality of stirring blades, each of which is evenly arranged at the bottom of the telescopic device 7, and the driving mechanism drives the stirring blades to rotate.
